The number of whales in a pod can vary significantly depending on the species. For example, killer whales (Orcinus orca) often live in pods of up to 40 individuals, while bottlenose dolphins (Tursiops truncatus) may live in pods of up to 100 individuals.
Whale pods are often led by a dominant male or female. This individual is responsible for making decisions about where the pod will go and what they will do. The dominant whale is also responsible for protecting the pod from predators and other threats.
Whale pods are important for social interaction, cooperation, and protection. They also help to maintain the genetic diversity of whale populations. By living in groups, whales are able to better survive and reproduce.
